2 Important information/Safety instructions

2.1 General safety precautions

Warning This appliance can be used by children aged 8 years and above, and

by persons with reduced physical, sensory or mental capabilities or

lack of experience or knowledge, provided that they are supervised or

have been instructed in the safe use of the appliance and understand

the hazards involved. Children must not clean or carry out user main-

tenance on the appliance except under adult supervision.

Warning Ensure that children do not play with the product.

Warning The installation must only be carried out by a qualified installation en-

gineer, following applicable rules and regulations in addition to these

installation instructions.

Caution The heat pump must be located in a frost-free environment!

Caution Installation and connection should be carried out in accordance with

the instructions, in order to avoid subjecting local residents to noise

disturbance.

Caution The heating appliance should be placed on a stable surface that can

support the gross weight of the heating appliance.

Caution Before the heat pump is powered, you must ensure that the heating

system and coolant system, including the heating pump, are full and

bled; otherwise, their circulation pumps may be damaged.

Caution If the electrician wishes to test the electrical connections before the

above is carried out, this should only be done after ensuring that the

heat transfer fluid pump and coolant pump are disconnected.

Installation Guide DHP-M

VMJSB202 Danfoss Heating Solutions

Caution When filling the coolant system the coolant pump must be operating;

you must ensure that the compressor and the heat transfer pump can-

not start.

Caution This appliance is intended for use by expert or trained users in shops,

in light industry and on farms, or for commercial use by lay people.

Caution In accordance with EN60335-2-40, this product is classified as "not

available to the general public." This means that the product is de-

signed to be handled by trained staff and installed in an engine room

or similar.

Caution Isolate the power supply to the heat pump while servicing the appli-

ance or replacing parts.

Caution Only spare parts approved by Danfoss Värmepumpar may be used for

this appliance.

In normal operation the heat pump generates noise and vibrations.

The appliance should be set up and connected in accordance with the

instructions in order to avoid noise being spread to noise-sensitive

areas.

2.2 Refrigerant

2.2.1 Refrigerant

Caution Work on the refrigerant circuit must only be carried out by a certified

refrigeration engineer.

Although the heat pump's cooling system (refrigerant circuit) is filled with a chlorine-free and environmentally-approved refrigerant that

will not affect the ozone layer, work on this system may only be carried out by authorised persons.

Installation Guide

DHP-M

Danfoss Heating Solutions VMJSB202

2.2.2 Fire risk

The refrigerant is not combustible or explosive in normal conditions.

2.2.3 Toxicity

In normal use and normal conditions the refrigerant has low toxicity. Even though the toxicity of the refrigerant is low, it can cause injury

(or even death) in abnormal circumstances or if deliberately abused.

Warning Risk of personal injury! Spaces in which heavy vapor can collect below

the level of the air must be well ventilated.

Refrigerant vapour is heavier than air, and in enclosed spaces or in areas below the level of the door, for example, seepage can give rise

to high concentrations with a resultant risk of suffocation due to lack of oxygen.

Warning Risk of personal injury! Refrigerant exposed to a naked flame creates a

poisonous irritating gas. This gas can be detected by its odor even at

concentrations below its permitted levels. Evacuate the area until it

has been sufficiently ventilated.

2.2.4 Working on the refrigerant circuit

Caution When the refrigerant circuit is repaired, the refrigerant must not be re-

leased from the heat pump - it must handled appropriately.

Draining and refilling must only be carried out using new refrigerant (for the amount and type of refrigerant see manufacturer's plate)

through the service valves.

Caution All warranties will become void if a refrigerant, other than what Dan-

foss specifies, is used for refilling.

2.2.5 Scrapping

Caution When the heat pump is to be scrapped the refrigerant must be extrac-

ted for disposal. Local rules and regulations related to the disposal of

refrigerant must be followed.

Installation Guide DHP-M

VMJSB202 Danfoss Heating Solutions

2.3 Electrical connection

Warning Hazardous electrical voltage! The terminal blocks are live and can

cause death through electric shock. All power supplies must be isola-

ted before electrical installation is started. The heat pump is connec-

ted internally at the factory, for this reason electrical installation con-

sists primarily of the connection of the power supply.

Caution Electrical installation may only be carried out by an authorized electri-

cian and must follow applicable local and national regulations.

Caution The electrical installation must be carried out using permanently rout-

ed cables and must follow applicable local and national regulations. It

must be possible to isolate the power supply using an all-pole circuit

breaker with a minimum contact gap of 3 mm.

2.4 Water quality

Caution A normal heating system always contains a certain amount of corro-

sion particulates (rust) and sludge products from calcium oxide. This

comes from acid that is naturally occurring in the fresh water that the

system is filled with. It is not good practice to have to fill the heating

system regularly which is why any leakage in the heating system

should be repaired immediately. Normal filling should occur only once

or twice a year. The water in the heating system should be as clean as

possible, always position the dirt filter on the return line from the heat-

ing system to the heat pump, as close to the heat pump as possible.

Caution Hard water; Normally it is not a problem installing a heat pump in

areas with hard water because the normal operating temperature for

the hot water does not exceed 60°C. In areas where there are excep-

tional prevailing conditions with the water one can install a softening

filter, which softens the water, cleans any impurities and prevents the

build up of calcification.

3 Transport, unpacking and setting-up

3.1 Transporting the heat pump

Caution The heat pump must always be transported and stored upright in a

dry environment. Secure the heat pump so that it cannot tip over dur-

ing transportation.

Caution If the heat pump is laid on the incorrect side it may become seriously

damaged, as the oil in the compressor may run out into the pressure

pipe and thereby prevent normal functioning.

3.1.1 Unpacking

1. Check that there are no transportation damages.

2. Remove the packaging.

3.2 Setting-up the heat pump

3.2.1 Recommended location

Positioning the heat pump

▪

The heat pump should preferably be placed against an outside wall (see chapter 'Heat pump data')

▪

Do not place the heat pump against walls facing noise-sensitive areas.

▪

Avoid placing the heat pump in the corner of a room.

Installation Guide

DHP-M

VMJSB202 Danfoss Heating Solutions

▪

If possible, choose a location where the surfaces nearest the heat pump are soft. Avoid placing the heat pump close to large plas-

tered or tiled areas.

▪

The heat pump is fitted with internal vibration insulation. However, the degree of vibration insulation achieved depends on the

bearing strength of the surface the heat pump stands on. In order to achieve adequate vibration insulation, the heat pump should

be placed on a concrete floor with a thickness of at least 100 mm, or another surface with equivalent characteristics.

▪

In order to minimise noise generation from the heat pump, the sound plate (included) should be fitted when the heat pump has

been put into position.

▪

The heat pump must be level.

6 Piping installation

Caution To prevent leaks, ensure that there are no stresses in the connecting

lines

Caution Pipe installation must be carried out by an authorised installer

Caution Ensure that the pipe installation is carried out in accordance with the

dimensions and connection diagrams

Caution Bleed valves should be fitted if necessary

6.1 Safety valves

Warning Radiator systems with a closed expansion tank must also be equipped

with an approved manometer and safety valve. The safety valve

should be to a minimum of DN 20 and have a maximum of 6 bar open-

ing pressure, or according to country-specific requirements.

Warning The overflow pipes from the safety valve must not be closed off. The

pipes should discharge into an outlet in a frost-free area.

Warning The connecting pipe between the expansion tank and the safety valve

must slope continuously upwards. A continuous upwards slope means

that the pipe must not slope downwards from the horizontal at any

point.

Caution Cold and hot water pipes and overflow pipes from safety valves must

be made of heat-resistant and corrosion-resistant material, e.g. cop-

per.

▪

Insulate the supply and return lines.

6.3 Noise information

To prevent disturbing noise from the heat pump the following recommendations should be observed:

▪

The heat pump's pipe connections cause vibration. In order to prevent this vibration spreading to the heating system and frame,

the pipes should be connected and laid with particular care.

▪

The brine and heat transfer fluid should normally be connected to the heat pump by means of a flexible hose.

▪

Pipes must not be attached to walls facing noise-sensitive areas.

▪

In cases where attachment of pipes to sensitive construction elements cannot be avoided, special elastic pipe attachments should

be used.

6.4 Connection brine

6.4.1 Drill holes for brine pipes

Caution Ensure that the holes for the insert pipes are positioned so that there is

room for the other installations.

Caution The brine pipes shall have separate lead-ins. If the wall lead-ins are be-

low the highest ground water level watertight lead-ins must be used.

The brine pipes must be insulated from the heat pump, through the walls and outside the house all the way to the collector so as to

avoid condensation and prevent heat loss.

If the brine pipes are to be routed above ground, drill holes in the walls for them.

If the brine pipes are to be routed below ground see the instructions below.

1. Insert pipe

2. Brine pipe

3. Mortar

4. Sealant

1. Drill holes in the wall for the insert pipes (1) for the brine pipes. Follow the dimension and connection diagrams. If there is any risk

of groundwater infiltration at brine pipe lead-ins, watertight grommets must be used.

2. Position the insert pipes (1) in the holes sloping downwards. The inclination must be at least 1cm every 30 cm. Cut them at an angle

(as illustrated) so that rain water cannot get into the pipes.

3. Insert the brine pipes (2) into the insert pipes in the installation room.

4. Fill in the holes around the lines with mortar (3).

5. Ensure that the brine pipes (2) are centered in the insert pipes (1) so that the insulation is distributed equally on all sides.
